Abstract: A cylinder actuator includes two elements mobile one relative to the other along an axis of movement and a position sensor configured to measure the relative position of the two elements, the position sensor comprising a multi-pole magnetic strip secured to a first of the two elements and a sensitive element sensitive to magnetic-field variations and secured to a second of the two elements, the multi-pole magnetic strip having an alternation of north and south poles extending in an interval that defines a measurement range for the measurement of the relative position along the axis of movement, the sensitive element being arranged in such a way as to detect variations in the magnetic field in the vicinity of the multi-pole magnetic strip along the axis of movement within the interval.
